Platystele oxyglossa...or not?

[Yéri]

Hi all,

I bought these 2 Platystele's early last year, both named as Platystele oxyglossa even though they seem to be very different plants (flowers as well as leaves). Also, when searching for this species in Google, I come up with very different flowers.

Anyone out there capable of ID'ing even one of these two plants? First two pictures belong to one plant and last two to the other.
